7 Claims.

The present invention relates generally to improvements in the art of facilitating the handling and distribution of certain delicate commodities; and relates more specifically to improvements in the construction and operation of cartons for holding confections such as batches of ice-cream or the like, during merchandising thereof, and while the confections are being eaten.

An object of the invention is to provide an improved confection holding carton or the like, which. is simple in construction and eflective in use.

The dispensation of certain delicate confections such as ice-cream in batches, has heretofore involved many problems, and it has previously been proposed to provide a relatively compact six sided collapsible carton, which when distended, would hold a bar of ice-cream while being eaten. One of these prior cartons was formed of a single cardboard blank having a rectangular front panel foldably connected to another wider. rectangular panel provided with a lower tapered extension and a substantially rectangular end flap depending therefrom., The opposite sides of the wider panel and of the tapered extension were scored and foldable to provide a central rear wall panel of the same width as the front panel, and to also provide two relatively foldable side walls at each of the opposite sides of the assembled carton, each set of side walls having an integral depending triangular ear at the lower extremity thereof. The lower tapered extension was additionally scored and foldable to provide a bottom which was loosely cooperable with the triangular ears of the side walls, and the bottom thus produced was secured to the lower portion of the rectangular front wall panel by adhesive applied to the rectangular flap.

While this prior six sided collapsible holder was relatively satisfactory for its intended purpose, the looseness between the bottom and the opposite side ears did not prevent molten icecream or other confection, from leaking through the lower portion of the carton; the provision of the rectangular lower flap made it necessary to waste considerable cardboard stock in producing the blanks; and the formation and fastening of the bottom forming extension did not tend to positively retain the container in properly spread condition so that the confection could be readily inserted within the distended structure.

It is therefore a more specific object of my invention to provide various improvements in the formation of this type of six sided collapsible cartons, whereby the cost of construction is reduced to a minimum, while the efliciency thereof is enhanced to a maximum.

Another specific object of the present invention is to provide an improved collapsible holder for ice-cream or the like, formed of a single blank of cardboard or similar sheet material, and having a simple leak-proof bottom.

A further specific object of this invention is to provide an improved six sided box assemblage formed of cardboard or the like, and which is adapted to be expeditiously produced with minimum waste of stock.

Still another specific object of the invention is to provide an improved collapsible carton assemblage in which the construction of the bottom closure and its attachment, is such that the structure will distend with a snap action, and will be positively maintained in distended position so that insertion of the commodity is readily possible.

These and other specific objects and advantages will be apparent from the following detailed description.

A clear conception of the several features constituting the present improvement, and of the mode of manufacturing and of utilizing confection holding cartons made in accordance with the invention, may be had by referring to the drawing accompanying and forming a part of this specification wherein like reference characters designate the same or similar parts in the various views.

Fig. 1 is a plan view of one of the improved,

carton blanks, viewed from the outer side;

Fig. 2 is an enlarged direct front view of the lower portion of the carton only partially assembled;

Fig. 3 is a fragmentary view similar to that of Fig. 2, showing the carton completely assembled and in collapsed condition;

Fig. 4 is a front and top perspective view of one of the assembled cartons, showing the same partially distended;

Fig. 5 is a front and bottom perspective view of the assembled carton, showing the bottom closure snapped into distended position, and a confection bar inserted; and

Fig. 6 is a full top view of the distended and confection laden carton.

While the invention has been shown and.described herein as being specifically embodied by way of illustration, in a six sided cardboard carton especially adapted to hold a bar of ice-cream or the like, it is not the intent to thereby unnecessarily restrict the scope or utility of the present improvement.

Referring to the drawing, the improved conlection holding carton shown therein may be formed of a one-piece or single cardboard blank such as shown in Fig. 1, and this blank comprises in general an approximately rectangular elongated front wall or panel 8 bounded at its opposite sides by score lines 9, Ill, and at its lower end by a transverse score line H; a similarly shaped rear wall or panel l2 bounded at its opposite sides by score lines l3, l4 and at its lower end by a transverse score line l5 located in horizontal alinement with the score line II; a pair of similar adjoining side walls I 6, l1. foldably interconnected along a central score line l8 and being connected to the front and rear panels 8, l2 at the score lines 9, [4 respectively, the lower ends of the side walls l6, 11 being oppositely inclined to provide an integral triangular ear [9; a pair of similar opposite side walls 20, 2| foldably connected to the front and rear panels 8, l2 respectively along the other side score lines l0, l3, and having their lower extremities oppositely inclined and cooperable to provide an integral triangular composite ear 22; an elongated side assembly panel 23 foldably connected to the side wall 2| along a score line 24 and having adhesive 25 on its inner side; a trapezoidal transverse bottom panel 26 interposed between the ears 19, 22 beneath the front panel 8 and foldably connected thereto along the lower score line I l; a similar trapezoidal transverse bottom panel 21 interposed between the ears I 9, 22 beneath the rear panel I 2 and being foldably connected thereto along the score line I5; and a lower transverse tapered extension or assembly panel 28 foldably connected to the lower edge of the panel 21 along a. score line 29 and having adhesive 3|] on its inner side.

As previously indicated, each blank may be formed of a single sheet of cardboard or similar sheet stock, and the successive blanks may be quickly and accurately produced with the aid of punches and dies. The carton blank may be of any desired vertical length; and may be provided with one or more transverse lines of perforations 3| so as to permit convenient removal of successive sections thereof, and the assembly panel 23 may also be formed with an elongated r side tab 32 for facilitating such removal of the sections. The adhesive 25, 38 is applied only to the inner sides of the assembly panels 23, 28 as clearly shown in Fig. 2; and while the vertical score lines 9, It! at the opposite sides of the front panel 8 are preferably extended downwardly across the bottom panel 25, the other vertical score lines I3, I 4 at the opposite sides of the rear panel [2 need not be carried across the lower panels 21, 28. The bottom panel 26 is also preferably formed of slightly less vertical width than the other bottom panel 21 as indicated in Figs. 1 and 2; and both of the bottom panels 26, 21 are foldably connected to the adjacent ears i 9, 22 along diagonal score lines 33 as shown. The blanks may obviously be produced with very little waste of stock, since each complete blank is approximately rectangular, and the assembled cartons are adapted to receive and hold rectangular prismatic bars 34 of any desired confection such as ice cream.

The completed carton blanks, shown in Fig. 1, may be stacked and either stored or shipped in compact form, and when it becomes desirable to assemble such a blank, this can be readily effected in the following manner. The blank may be positioned and initially folded along the medial score line l8 to position the front wall 8 above the rear wall i2, and to simultaneously position the side wall i6 over the side wall l1 and the side wall 20 over the side wall 2i. The bottom panel 26 will then be superimposed over the bottom panel 21. The areas of adhesive 25, 30 may then be moistened and the assembly panels 23, 28 may be folded inwardly along the score lines 24, 29 respectively so as to superimpose the adhesive panels 23, 28 over the adjacent panels 20, 26 respectively. The assembly of the carton is thus completed and the completed cartons when in collapsed position as shown in Fig. 3 may likewise be stacked and stored or shipped in compact form. a

When it becomes desirable to distend one of the cartons for the reception of a bar 34 of confection or the like, the collapsed carton should firstbe spread at the top as illustrated in Fig. 4. Pressure should then be applied to the medial portion of the carton along the lower score line 29, and this application of pressure will snap the bottom panels 26, 21 and the lower assembly panel 28 upwardly so that the mid-portions of these panels will lie in a plane at the lower extremities of the front and rear walls 8, l2 while the opposite side portions of the bottom panels will coact with the ears I9, 22 as shown in Fig. 5, to thereby lock the carton in distended position. Due to the fact that the adhesive 30 covers the entire irmer surface of the assembly panel 28, the entire bottom of the carton will be firmly united and thoroughly sealed so as to preclude possible leakage of liquid through the bottom. The slight weakening of the bottom panel 26 by extending the score lines 9, l0 thereacross will be sufficient to permit the bottom panels to be snapped upwardly after the carton has been assembled, and when this snap action takes place, creases 35 will be formed across the bottom adjacent to the ears I9, 22 (as clearly illustrated in Fig. 5. The bar 34 of confection may thereafter be inserted within the distended carton, without danger of having the carton collapse, and the several sections of the carton structure may be subsequently removed with the aid of the perforations 3|.

From the foregoing detailed description it will be apparent that the present invention provides an improved confection holding carton which is extremely simple in construction and highly effective in use. The improved carton structures may obviously be formed of relatively simple blanks with minimum waste of stock, and either the blanks or the assembled collapsed cartons can be conveniently stacked and confined within limited space. The construction of the improved carton is obviously such that it may be readily distended and locked in distended condition, and the formation of the bottom of the carton is such that a tight seal is provided and leakage of liquid from within the carton is positively prevented. The improved assemblage has proven highly practical in actual commercial use, and can obviously be manufactured and sold at moderate cost.

It should be understood that it is not desired to limit this invention to the exact details of construction, or to the precise mode of use, herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
